To CLU, whom t 71mg/ cmzceru: 1 I Be it known that I, PETER FARLEY, va citizen of the United States, anda resident of. Glenridge. in the county of Essex andlState of New Jersey, have invented certain new and useful Improvements in Riveted Joints, ofl Vwhich the following is a specification.V1 f v This invention relates to improvements in`v` riveting orfiolding-together metals, :ind more f especially-for riveting together the sheets o`r plates yof steel or iron formingwater co'r'iduitsn or pipes, ships.- hulls, `boilers, te.; andl it;

consists, essentially,of an improved riveted goint.

. The object is to maken tiglitjoint,V so'a`s tov K prevent rusting of the rivet or metal and consequent lenkege'- and to .avoid-calkingf3 of the joint. These objects are attained in the manner and by the means hereinafter described and claimed, reference heinghald to the accompanying dreivingsin whichf.

Figure lshows an ordinarysteel rivet with lmy improved (talking-Sleeve invertical Section. Fig.- 2 showsin vertical section the sii-nie sieeve inserted inthe rivet-hole of two plates of steel or iron readyto be riveted.

'Fig 3 shows the twio. sheets .of metal and the improved calliing-sl'eei-*e in vertical section, the sleeve insertedin" the rivet-holes, and the rivet in piece-in the sleeve.- Fig. eis the sinne view as shown in Fig. 3, but with the rivet partially upset. l Fig. 5 showsin vertical section the sinne sheets of metal as shown in Figs. Sand i with the rivet-head formed' and the improved milking-sleeve forced int'o the space between the two heads.v the calliing-sleeve in vertical section slipped on over a rivet beforeheiiiginserted into the rivet-holes of the plates. Fig. 7 shows an end View of two lengths of water-pipe riveted together, the inner pipe being shown in transverse sect-ion, the Whole showing complete my improved riveted joint. Figs. Sand 9 are plan 'views oftwo plates of metal riveted, thetirst being single-riveted and the second being double-riveted, both riveted iu accordance with inyiiivention. Figs. l0, ll, and lshow a. modiiieation in construction of the annular head or shoulder on one end of the improved sleeve forming a, part of my improved riveted Fig. 6 shows Y tion the sleeve with rivet ready to'he inserted, the second "Showing a seotionalvieivof fthe riveted sheets,Withsleeve'iiiserted in the rivet holes,an`d .the third showing the'rivet upset andriveted{inplace..ifz Similar referencerinarks rei'efr to similar .throughoiit theseveral drawings.

At 4 .I'have ashell lor .callziugsleeye made `preferablyofsoft'copper or brass. or zine, or

ofgfsuitablel length for.. riveting together the ljoint, the iirstigure'showingin vertical secsh-oyvanfordiiiaiyfironor steelrivet l some suitable/,alloy which is soft and pliable and yet of-a metal or alloy which melts et a suitably high temperature so that when hot rivets are used they Will not'inelt this sleeve. The preferredconstruction-of this sleeve 4 isfis shoivninligs.v 1, Zand 3, with lone end of the shell slightly thieker'or having thereon .an annular head, projectiomor shoulder, as shown it 5 end 5', so that when inserted in the rivet-holes of the metal plates it willnot drop through, 'but will fit tight and rest on the plate @against the shoulder or thick edge 5 or 5", as shown in Fi 2. This sleeve 4 not only should tit the rivet holes tightly and rest on the shoulder 5, but ii. is made, preferably, longer than the combined thickness of the two plates l and 2, so that the end 6 'stands out 'a trie beyond the plate it. as shown in Figs and 4, and the fend vviti. the shoulder 5 also stands out a triiie beyond the other plate, l; but this sleeve .is pre-ter iblyof less length .than the shank of the rivet used, as shownin Figs. 3 and 6.' The shoulder oit-annular head V5 or 5 is necessarily .of larger outside diameterlthan the shelL'shank, or main lpart of said sleeve, but preferably ot' less ont side diameter than the head of the rivet used .'therewith. I v- =When the rivet is upset. or partially riveted, as shovvn in Ffnnd, the body or shank of the rivet `is thickened, end it-is made .to fill the sleeve tightly, aiidfwhen the plates'ere fully riveted together and the rivet-head is foi-ined I .as shown in Fig. the- Sleeve 4 is shortened erger renee si.

and the shell mede thicker, that it is forced into all the grain and inequalities' of the edges "acted in piene whenniy improved s of the plates 1 l(md 2 lround the rivet-holes and in the inner side oi' the rivet-heads, thus .'cnlking the rivet, as it were.l More or less of the metal of the sleeve is also forced into the 'crevices around the rivet-holev'fhere the two platescome together, the outer surface of .the sleeve 4 taking ou 'the shape of the rivet-hole, es shown in Figs. 5 and12, and filling all the inequalities, and the' rivet is calked, as it'i were,` Aalso by theends ofk thesleeve or shell 4 5-being forced into the under or inner side of'. :aeh'of' the rivet-heads, as shown inf-Figs 4end l2. As the rivet cools' and contacts this e'alking is mede tighter. No Watereen get into the shank 3 of the rivet after theii t is riv- "e form;

fing a pnrtf my improved rivetedfjoint is used bfrewitmnor under the rivet-heads, and the i A siee've being made-of, e' nou-corrosive 'metal or alloy thus corrosion and'rust `and consequent leakage are avoidedi Y The sleeve 4: should be made of such suitable size so as to tit tightly into'the rivet-holes of the plates arid-also tightly around the shankn of the rivet, preferably a driving fit in each case, audit should be-oflsu'ch suitable ,length so thatwheuthe plates are tightly riveted together. the heads 'are set up tightly against the plates, arid the surfaces of the two plates are also forced tightly together, and so that the sleeve is forced to till all the annular space between rivetshank and the edges of. the

plates inside the rivet-holes and the ends well cnlked against the inner side of hot-h rivetn heads, 4sind the outer edges of the rivet-hends when riveted should ine'ernhly ley eown close to the outer surfaces ot the plates. as shown in Figs. 5 und i2. These advantages are specially secured by use oi my improved calking-sleeve,forming a part oif my improved riveted joint, When'ninde of the substantially relative proportions :is to the rivets used there4 with and as to the thickness of the steel or iron plates tobe riveted and calked, the rela-tive length ofsleeves and the relative diameter of theA annular shoulder thereon as to thickness 'ofv plates and length oi' shank oi' rivets used end., overlying the respective flange of the sleeve', substantially as shown and described. Signed at Glenridge, in the con nty of Essex and State of New Jersey, this' 19th dey of September` A. l). 1903.
